I have two DCS-8526LH mounted on ceiling (Invert Image is ON) and both have the same issues.
After few days, I found both the cam pan to right a bit. After more days, the cams pan to further right. If I restarted the cam, both at the home center normally. Now, I'm using 2 smart plugs to schedule stop/start the cams everyday.
Is that only this model or firmware 1.08.01 has this problem? Is there other D-Link Wifi pan-tilt cams also have this problem?
